<dt><em>Description</em>:</dt>
<dd><p><code>IARGC</code> returns the number of arguments passed on the
command line when the containing program was invoked.

<p>This intrinsic routine is provided for backwards compatibility with 
GNU Fortran 77.  In new code, programmers should consider the use of 
the <a href="COMMAND_005fARGUMENT_005fCOUNT.html#COMMAND_005fARGUMENT_005fCOUNT">COMMAND_ARGUMENT_COUNT</a> intrinsic defined by the Fortran 2003 
standard.
